[SCSI] arcmsr: updates (1.20.00.15)
- add arcmsr_enable_eoi_mode()and readl(reg->iop2drv_doorbell_reg) in arcmsr_handle_hbb_isr() on adapter Type B in case of the doorbell interrupt clearance is cached - add conditional declaration for arcmsr_pci_error_detected() and arcmsr_pci_slot_reset - check if the sg list member number exceeds arcmsr default limit in arcmsr_build_ccb() - change the returned value type of arcmsr_build_ccb()from "void" to "int" returns FAILED in arcmsr_queue_command() - modify arcmsr_drain_donequeue() to ignore unknown command and let kernel process command timeout. This could handle IO request violating maximum segments, i.e. Linux XFS over DM-CRYPT. Thanks to Milan Broz's comments <mbroz@redhat.com> - fix the release of dma memory for type B in arcmsr_free_ccb_pool() - fix the arcmsr_polling_hbb_ccbdone() Signed-off-by: Nick Cheng <nick.cheng@areca.com.tw> Cc: Milan Broz <mbroz@redhat.com> Cc: <thenzl@redhat.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: James Bottomley <James.Bottomley@HansenPartnership.com>
